US Pacific Coast Seaweed Shows With Fukushima Cesium Contamination

New testing done by Worcester Polytechnic Institute, Dept. of Civil and Environmental Engineering found Fukushima cesium in US Pacific sea weed. The samples were standardized against a known amount of cesium 137 and cobalt 60. The finding of cesium 134 would indicate this is at least partially from the Fukushima nuclear disaster.

“One of two Japanese nori samples from a Chiba Prefecture market contained 1.1 pCi/g of Cs134 and 1.7 pCi/g of Cs137. (That’s 41 and 63 Bq/kg, respectively.) The other was nondetect for these isotopes.”
